Amazon's connection with Facebook is about to go from "it's complicated" to "in a relationship." In a bid to make its listings more social, the online retail giant has begun contacting customers to notify them that it will soon start showing product reviews and "wishes" from their Facebook friends. If you're browsing Amazon's Chromecast listing, for example, the company will let you know if any of your Facebook connections have either reviewed the $35 streaming dongle or are not-so-secretly indicating for someone to buy it for them. It's not the first time the retailer has leant on Facebook's Social Graph: earlier this year it launched Birthday Gift to help you buy your Facebook friends something nice and let others contribute. Amazon's new feature lets you opt-in on its Social Settings page, and will only display your Wish List items if you decide. Just remember that before writing that glowing review of the latest Nickleback album.
